Our study focuses on InformationTechnology (IT) project teams in organizations located in Sweden. The rapid growth oftechnology and IT sector, increasing demand in IT professionals, and the knowledge ofwriting universal code allow people to work internationally regardless of citizenship.Therefore, the workforce in the IT sector is rapidly growing and diversifying — it ischaracterized by teams consisting of different nationalities. However, these differences incultures, languages and nationalities can complicate the communication processes betweenthe team members. Therefore, efficient cross-cultural communication within a team isessential for team collaboration and performance. Purpose: The study aims to find the significant issues in the process of adaptation to the newculturally diverse environment faced by immigrant professionals in IT project teams. Thestudy mainly focuses on an individual level, consequently expanding it to a collective level,as the related challenges refer to collaboration among the team members. Method: The study was conducted by interviewing immigrant professionals who have beenworking in IT project teams in the companies, located in Sweden. The participants belong tosix different nationalities and have worked in Sweden for approximately 2-8 years. They areall male aged between 30-33 years old. After the interviews, we can present findings, whichdemonstrate the points of similarity and difference. Conclusion: Technology, which is a significant factor in IT projects, constantly changes, andtherefore, IT project teams that work with innovation require high adaptability to explore newopportunities. That makes effective coordination and communication essential. In theculturally diverse team, managers should manage global mindset and cultural intelligence forindividuals to help team members in adaptation process.
